10. Trisaba

$z =\frac{ 4 }{ 7 }$

11. Trisaba

how do i use z score on that though it is repeating

12. anonymous

yea.. this is sort of confusing, but yea that i see the example. :) I am pretty sure that is the right answer. Just put the little line over the number that is repeated.

13. Trisaba

no like if z = 0.7 i have to do find where 0 and .7 intersect

14. Trisaba

i cant use that cause it is repeated

15. anonymous
